CARDING-MACHINE.

reac es.

To all whom it may concern:

Be it known that I, ELWIN H. RooNEY, a citizen of the United States,residing in l fhitinsville, Massachusetts, have invented the followingdescribed new and useful Improvements in Carding-lVlachines.

The object of this improvement in carding machines is to provideeffective and practical means for removing the dirt which collects inthe card clothing of the card and dofler cylinders. The mechanismincludes rollers which are moved into and out of engagement with thecard-clothed cylinders, together with means for effecting such movementautomatically and positively acting means for automatically connectingand disconnecting the rollers and their driving means, whereby therotation of the rollers is started and stopped at exactly determinabletimes in the cycle of operations and the driving of the rollers is inone direction and during brief periods only, the result of thiscombination being to secure a high degree of efficiency and to avoidunnecessary wear and complication. With the stripping rollers, whichengage the cylinders, are associated clearing rollers, mounted on thesame movable supports and connected to he driven at greater surfacespeed than the strippers, in order to take the-strippings therefrom. Areceptacle for receiving the material from the clearing roller is alsomounted on the support with each pair of rollers, so as to be moved toand fro there with. The device thus constituted is brought intoengagement with the card cylinder or the doffer cylinder, as the casemay be, at intervals, the rollers are driven while in the said positionand for a brief period after separation from the cylinder, to permit therollers to clear themselves, and then become stationary, in whichcondition they remain for a substantially longer period than that duringwhich they were driven. Other features of the invention will berecognized by those skilled in the art as the specification proceeds.

In the accompanying drawings:

Serial No. 23,282.

Fig. 2 is a side elevation, on an enlarged scale, illustrating moreparticularly the mechanism for moving the rollers to and from thecard-clothed cylinders;

Fig. 3 is a detail side elevation of one of the lower roller-carryingarms;

Fig. 4 is a view in end elevation and partly in section of the generalmechanism;

Fig. 5is anenlarged cross-section through the cam member;v

Fig. 6 is a face view thereof;

Fig. '7 is an enlarged side elevation of the roller mounting at theupper end of the upper roller support; and

Fig. 8 is a f 'agmentary elevation, partly in section, looking at rightangles to Fig. 7.

In these views 11 is the card cylinder and 12 the-dolfer cylinder, bothprovided with appropriate card clothing. The dolfer cylinder is showndriven from the card cylinder shaft by a band 13, which passes aroundpulleys on the shafts of the cylinders and about a binder pulley 14.Other details of known construction in carding machines are omitted asunnecessary to an understanding of the improvements.

The devices for removing the dirt from the card clothing of thecylinders comprise two sets of rollers 15 and 16 and 15 and 16 one setbeing above and operative upon the doffer cylinder and the other belowand operative upon the card cylinder. These rollers are likewise coveredwith card clothing, and 15 and 15 are the stripping rollers to engagewith the cylinders, and 16 and 16 the clearing rollers designed to takethe strippings from the stripping rollers.

Each pair of rollers is mounted for movement to and from its cylinder.The upper is carried by a support comprising a pair of swinging arms 17connected by a crossrod 18. Only one of the arms is shown inthedrawings, it being understood that the arms at opposite sides of themachine are symmetrical duplicates. In like manner the lower set ofrollers is journaled in a swinging support comprising arms li of whichonly the arm at the near side of the iachine is illustrated. At eachside of the machine the arms 17 and 17 are mounted on a common hearingor support consisting of a fixed shaft 19 projecting from a bracket 20,which in turn is fastened to a suitable frame part 21.

The means for swinging the roller-carry ing arms comprises a cam wheel28 mounted on a shaft 28 and driven from a longitudinal countershaft 24by a worm 25 on the countershaft meshing with a worm wheel 26, which hascompounded with it a pinion 27, (see dotted lines Fig. 1), the lattermeshing with the cam-gear 28. By a gear train of this or other suitablecharacter the cam is rotated at a low rate of speed appropriate to thepurposes of the invention. There is preferably one of these cam membersat each side of the machine, but the driving train occurs only at oneside since both members are fixed to the same driven shaft 23.

As more particularly illustrated in Figs. 5 and 6, the said cam memberis composed of an outer part 29 and an-inner part 30, formed,respectively, with cam grooves 31 and 32. The outer part is united withthe hub 33, beinginteg'ral in the present case, and the innerv part isan annulus occup the recess between this hub and the inner Wall of thegroove. 31. The two parts are held together by bolts 34, which occupyadjustment slots 35 in the part 30, permitting the cams tobe angularlyadjusted with reference to each other and to the proper tiniing of theparts. The outer cam groove (31) controls a roller stud 36 (Fig. 2)projecting into it from the lower end of the upper arm 17, and the innergroove similarly receives a roller stud projection 86 onthe other arm17, the connections of the roller-studs to their respective arms beingslotted as indicated to permit of adjustment. The contour of the camgrooves issuch that their major portions are concentric with the axis,the eccentric portions being relatively limited in extent. It resultsfrom this and from the slow movement of the cam that the rollers areheld most of the time away from the card and doffer cylinders and arebrought into engagement therewith for brief periods only and atcomparatively long intervals.

upper rollers through a band 44. Band at is trained so that both itscourses pass at the same sides of pulleys 45 and 46 (Fig. -i) of whichone is fast and one loose, on the journal extension 17 of the strippingroller 15, and around a single pulley 28 fast on the journal extension49 of the clearing roller 16. Belt 4 :3 cooperates in like manner withfast and loose pulleys a5 and a6 on journal extension 4-7 and pulley 1 8on journal extension 4L9, of the lower rollers.

The clutch faces of the driving elements 39 and i0, formed as cones 50in the present instance, are normally separated by a spring 51, butother forms of clutches are equally serviceable. The said clutch iscontrolled positively and automatically in accordance with the camcontrol of the swinging arms, thus insuring the rollers being set inmotion at the proper moments and the driving thereof being continuedthroughout the period for which it is desired they shall r0 tate. Tothis end the member :10 is mounted slidably on the shaft 19 and isshifted by a lever 52, which latter is fulcrumed intermediate its endson a pin fixed adj ustably in a slot 54; in a stationary arm 55projecting from the bracket 20. The lower end of this lever carries aroller bearing 56, cu gaged at intervals by a cam 57 on the face of thecam disk 28, which automatically closes and opens the clutch, atpredetermined intervals, the opening movement taking place by virtue ofthe spring 51. Manifestly, if desired, the spring could be dispensedwith and the cam caused to operate the clutch lever positively in bothdircctions. For purposes of adjustment the cam piece 57 is formed with acurved slot 58, through which passes a screw 59 securing it to the cammember 29.

It will be observed that the ratios of the various elements of thedriving means of the rollers are such that the lower rollers are drivenfaster than the upper rollers, since the card cylinder revolves at ahigher speed than the doffer; furthermore, the clearing roller of eachpair is driven faster than the stripping roller and in the oppositedirection. It will also be understood that each stripping roller isdriven at greater surface speed than the card-clothed cylinder withwhich it engages. in order to take the dirt therefrom.

It will be further understood that the roller driving elements, theclutch. clutch lever and cam piece 57 need not be duplicated at bothsides of the machine, since it is sufficient to drive the rollers byCOIlI10C- tions engaging them at one end.

The mounting of the rollers on the arms is illustrated more particularlyin Figs. 7 and 8. The upper arms 17 have bearings (30 at their upperends, through which pass the roller journals 4-7, and end plates 61, atopposite ends of the rollers, have each a hub portion 62 receiving theadjacent journal and entering the bearing in the arm.-

inte ers in angular positions, thus adjusting 1311830163.?" ing, rollerabout the stripping roller. The plate is also apertured to accommodate abearing 66 for the journal of the clearing roller, and this bearing ismade rectilinearly adjustable toward and from the stripping roller byslide engaging portions 67 nor mally clamped by a screw 68. Themounting,

metal to constitute eXtensions of the casings, extend the full length ofthe rollers, and can readily be connected with an exhaust forautomatically Withdrawing the dirt as deposited.

In Figs. 1 and 2 it will be observed that the various cam elements areso set as to be in action at the same time. According to the preferredtiming the face cam 57 rides beneath the roller of the clutch lever 52and throws in the clutclnso as to start the rollers revolvingimmediately before or just as the cam groove 32 causesthe lower arms 17to swing the stripping roller 15: into engagement with the. cardcylinder. Next, and preferably before the said. roller has left the cardoylinder,-the cam groove 31 brings the upper set of rollers intooperative relation to the doifer cylinder. The lower rollers are nowreturned to normal position and directly thereafter the upper rollersare restored. Manifestly, however, the two sets of rollers could beshifted simultaneously or in the reverse order,if preferred Finally, theface cam rides out from beneath the clutch lever and the rollers ceaserevolving, butthe length of the face cam is such that this does notoccur until a short time has elapsed after the separation of the rollersfrom the cylinders, thus insuring the rollers making a' sufficientnumber of revolutions after stripping ceases to en-' able the clearingrollers to complete the re moval of the strippings from the stripperrollers and to deposit the same in the re ceptacles. The cams 31 and 32are so de signed, as indicated, that the lower stripping roller is heldagainst the card, cylinder for a longer period than that during whichthe upper stripper operates 011 the doft'er cylinder. The uniting of thecam, means for controlling the movable roller supports and also thedriving means into a compound cam device composed of relativelyadjustable parts is desirable for the compactness of the constructionand the facility which it af fords in regulating the timingof the operations. The mounting of the clutch 0n the same axis 'or hearing asthesupports is like- Wise advantageous in economy of spaceand parts, and inaddition obviates undesirable slackening or tightening of the bandsconnectingthe driving element l0 with the roll ers, when the supportsare swung to and fro. Various other advantages of the particularpreferred features of construction illustrated will be appreciated bythose skilled in the art.
